Detailed Description

National 710574 is a metric wheel seal engineered around precise dimensional fitment, including a 54.000 mm shaft diameter and 64.000 mm housing bore. The bi-directional lip design supports rear outer sealing needs where consistent oil retention and contamination control are critical.

• Noise or service issues caused by compromised wheel-end sealing

Installation Notes and Tips

Verify the shaft, housing bore, and width dimensions before installation to confirm the seal matches the axle assembly. Inspect the sealing surface for scoring, corrosion, or wear that could affect lip contact, and clean the bore thoroughly before pressing the seal into place. Confirm the rear outer position and the specific vehicle year, especially on the 2000 Tacoma with the 5/1/2000 note.
